I posted this in the wrong section, I don't mean to repost but I don't know my way around here so I'm copying this here.
Just bought an '81 Cadillac with the optional 4.1 252 Buick motor. I've been asking for help on the Caddy forums, but with it not being a common motor in these cars there's not too many Caddy guys with them so I was hoping I could get some help here. The car ran fine for the first two weeks I owned it. Wanted to do a little pm, so I put new plugs in. AC Delco factory spec. The next day the car sputtered during acceleration, bad. Thought I damaged a wire, so I replaced them, no change. Got new plugs thinking I had a bad one somewhere, no change. Fiddled with the EGR vacuum solenoid and it got much worse. Noticed one of the nipples on the solenoid was broken, so I fixed it, got a little better. Unplugged the EFE, because it was unplugged when I got the car, and it didn't make a difference. Checked the timing and it's around 20. I can't find any broken vacuum lines. I'm confused and frustrated.
I just want it to run smooth.
